Renewable power accounted for 70% of net additions to global power generating capacity in 2017, the largest increase in renewable power capacity in modern history, according to REN21’s Renewables 2018 Global Status Report (GSR). But the heating, cooling and transport sectors – which together account for about four-fifths of global final energy demand – continue to lag far behind the power sector. The GSR, published last 4th June, is the most comprehensive annual overview of the state of renewable energy worldwide.
